Transmission: after having the car stuck at the machine shop (doing some valve head repairs) which extended for over three months, I've noticed my transmission hesitating when starting (seems like clutch slippage). Wonder (hope) this is due to machine being down for so long. Next steps, check oil level, if ok, run car for over 1-2 hours to see if after warming up problem gets eliminated. Open to hear any expert advice. Best to all!
